Those commands are trying to load the entire line into memory at once, which won't work on a 64 32-bit system since there's a 4GB limit on per-process memory and sufficient clutter in the way that you probably can't get an entire 2.5G in one chunk.
How big are the individual records? You can tell awk to use things other than \n as a record separator, changing its definition of lines:
Use nawk or gawk if you have it.
